Patent

CA 2298563

The invention concerns a method for preparing substituted benzyl bromides of general formula (I), wherein at least one substituent R1-5 represents an electroattractive group, such as fluorine, chlorine, bromine, C1-C4 alkoxycarbonyl, cyano or nitro, and the remaining R1-5 substituents represent hydrogen or methyl, by bromination of substituted toluenes of general formula (II) with a bromination agent at temperatures from 20 to 95 ° C.

L'invention concerne un procédé pour la préparation de bromures de benzyle substitués de la formule générale (I), dans laquelle au moins un substituant R<1-5> représente un groupe attracteur d'électrons, tel que fluore, chlore, brome, alcoxycarbonyle C1-C14, cyano ou nitro, et les substituants R<1-5> restants représentent hydrogène ou méthyle, par bromation de toluènes substitués de la formule générale (II) avec un agent de bromation à des températures de 20 à 95 DEG C.
